FIG. 5 is a block diagram showing a circuitry construction of a control circuit 40 for controlling game operation process in the slot machine 1 of the embodiment.

The control circuit 40 is mainly constructed from a microcomputer 41 and the microcomputer 41 is constructed from a main CPU 42 (Central Processing Unit) for conducting control operation according to a program preset beforehand, a ROM (Read-Only Memory) 43 as a storing device and a RAM (Random Access Memory) 44. In the ROM 43, control procedures for wholly controlling the gamin machine are stored as a sequence program and the RAM 44 is utilized as a temporary memory work area and the like when such program is executed.

To the main CPU 42, a clock pulse generator 45 for generating standard clock pulses and a frequency divider 46, a random number generator 47 for generating random numbers within a predetermined range and a sampling circuit 48 for sampling one random number generated by the random number generator 47, are connected. Further, an I/O port 49 to receive and output various signals between peripheral devices (actuators) mentioned later, is connected to the main CPU 42. And the ROM 43 has also memory areas to store a winning combination table which is referred when the winning combination is determined based on a symbol combination, other than the sequence program.

Here, the microcomputer 41, the random number generator 47 and the sampling circuit 48 constructs a lottery device to determine the winning combination by a lottery and selects the symbols which are stopped and displayed on the display windows 6 to 8 or the liquid crystal display panel 5 d by a lottery and determines the winning combination based on the selected symbol combination. And the microcomputer 41 constructs a game medium storing device for storing the betted money inserted from the coin insertion slot 11 and the bill insertion portion 12 as data in the RAM 44.

As the main actuator the operation of which is controlled by a control signal from the microcomputer 41, there exist stepping motors 50 for rotating and driving the reels 2 to 4, various lamps 51, a LED display part 52, a hopper 53 for storing coins, the liquid crystal display panel 5 d and a speaker 55. These are driven and controlled by a motor drive circuit 56,a lamp drive circuit 57, a LED drive circuit 58, a hopper drive circuit 59, an image control circuit 60 and a sound control circuit 61, respectively, These drive circuits 56 to 59 and the control circuits 60, 61 are connected to the main CPU 42 through the I/O port 49.

And as the main input signal generation device for generating input signals necessary for the main CPU 42 to produce control signals, there exist a start switch 9S for detecting operation of the start lever 9, the spin switch 13, the change switch 14, the cashout switch 15, the 1-BET switch 16, the MAX BET switch 17 and a coin sensor 11S to detect coins inserted in the coin insertion slot 11. Further, a reel position detection circuit 62 for detecting the rotation position of the reels 2 to 4 is provided.

And as the input signal generation device, there exist a coin detection part 53S for counting the number of coins paid out from the hopper 53, a payout completion signal generation circuit 63, the numerical keypad device 35 constructed from the numerical keypad image displayed on the liquid crystal display panel 5 d and the predetermined area of the touch panel 5 k corresponding to the numerical keypad image and a numerical keypad device detection circuit 64. The payout completion signal generation circuit 63 generates a signal to detect a coin payout completion when the coin count value corresponded to the coin number actually paid out and input from the coin detection part 53S reaches to the payout coin number data. And the numerical keypad device detection circuit 64 detects operation of the numerical keypad device 35, such operation being done by touching the touch panel 5 k corresponding to numerical keys of the numerical keypad image displayed on the liquid crystal display panel 5 d and outputs the detected operation signal to the main CPU 42. The above payout completion signal generation circuit 63 and the numerical keypad device detection circuit 64 are also connected to the main CPU 42 through the I/O port 49. Here, the main CPU 42 constructs a denomination recognition device to recognize the numerical value input from the numerical keypad device 35 as the sum betted for one bet.

In the above construction, before the game is conducted in the slot machine 1, the play at first inserts coins in the coin insertion slot 11 or inserts a bill in the bill insertion slot 12, thereby the betted money is stored in the slot machine 1. Next, the sum betted for the game is directed by the player among the betted money which is stored. This direction is done by determining the denomination corresponding to the sum betted for one bet and the bet number.

On a game image displayed on the reel display window portion 5, as shown in FIG. 6, a character image 31, a denomination display part 32, a payout display part (WIN) 33 for displaying the payout number paid out to the player and a bet number display part (BET) 34 are displayed. When the touch panel 5 k corresponding to a periphery of the denomination display part 32 is touched, the numerical keypad image is displayed on the liquid crystal display panel 5 d as shown in FIG. 6, thereby denomination input operation is made effective through the numerical keypad device 35 constructed from the numerical keypad image on the liquid crystal display panel 5 d and the touch panel 5 k.

The numerical keypad device 35 is provided with numerical keys of “0”˜“9” and “00”, a clear key (CLEAR), a dollar ($) display key and a cent (¢) display key. Here, the numerical keys, the clear key are, the dollar display key and the cent display key are constructed from the numerical key images, the clear key image, the dollar display key image and the cent display key image included in the numerical keypad image displayed on the liquid crystal display panel 5 d and the touch panel 5 k. And the numerical value input by touching the touch panel 5 k corresponding to the numeral key images is displayed in an upper input numerical value area 35 a. For example, in a case that touch panel 5 k corresponding to the dollar display key image is first pressed and thereafter the touch panel 5 k corresponding to the numerical key images “1” and “0” are pressed in this order, and further the touch panel 5 k corresponding to the cent display key image is pressed and thereafter the touch panel 5 k corresponding to the numerical key images “5” and “0” are pressed in this order, “$ 10.50 (10 dollars and 50 cents)” is displayed in the input numerical value area 35 a as shown in FIG. 6. Thereafter, the numerical keypad image disappears at the timing that the player operates the start lever 9 or the spin switch 13 or the MAX BET switch 17 and the denomination is recognized as 10 dollars and 50 cents by the main CPU 42, thereby this sum is displayed in the denomination display part 32. In the first embodiment, the sum from 1 cent up to 100 dollars can be freely betted as the denomination by utilizing the numerical keypad device 35. And when the denomination is input by the numerical keypad device 35 according to the above, if a false numerical value is input, such numerical value can be corrected by pressing the touch panel 5 k corresponding to the clear key image and again inputting the correct numerical value by touching the touch panel 5 k corresponding to the numerical key images.

Next, the bet number is directed. This direction is done by operating the 1-BET switch 16 or the MAX-BET switch 17. For example, when the MAX-BET switch 17 is pressed one time, the bet number is recognized as 1000 by the main CPU 42. And when the 1-BET switch 16 is pressed desired plural times, the pressed times are recognized as the bet number by the main CPU 42.

When the bet number is recognized, the main CPU 42 sets the sum calculated by multiplying the bet number with the denomination directed according to the above as the betted money. And based on the operation of the start lever 9 or the spin switch 13 or the MAX BET switch 17 by the player, rotation process of the reels 2 to 4 is done and the slot machine game is started. And in a case that the symbol combination of the winning combination with payout is stopped and displayed along the pay line L, the payout corresponding to the betted money which is set by the main CPU 42 is given to the player. Thereby, the credit number is increased or coins are paid out to the coin tray 19.

According to the slot machine of the first embodiment, as mentioned, when the numerical value is input through the numerical keypad device 35 constructed from the numerical keypad image displayed on the liquid crystal display panel 5 d and the touch panel 5 k, such numerical value is recognized as the denomination by the main CPU 42. And the sum calculated by multiplying the denomination with the bet number set by the 1-BET switch 16 or the MAX-BET switch 17, is betted, thereafter the slot machine game is conducted. Thereby, the player can voluntarily set the denomination without being limited to the sum which is fixed beforehand, as in the prior art.

And in the first embodiment, the numerical keypad image is displayed on the liquid crystal display panel 5 d in the reel display window portion 5 which displays the game image of the slot machine 1, and the player can input the denomination by touching the touch panel 5 k corresponding to each of the numerical key images constructing the numerical keypad device 35 in cooperation with the touch panel 5 k. Therefore, the player can quickly operate the numerical keypad device 35 while seeing the reel display window portion 5 and operability to determine the denomination can be raised.

Next, the slot machine of the second embodiment according to the present invention will be described.

The slot machine of the second embodiment has the same construction as the slot machine 1 in the above mentioned first embodiment, except for the numerical value input device for setting the denomination which is different from that in the first embodiment.

FIG. 7 is an explanatory view of the reel display window portion on which a denomination selection panel for determining the denomination is provided to determine the denomination, according to the second embodiment. Here, in FIG. 7, the same numbers are added to the members, the elements having the same construction as those in the first embodiment.

Similar to the above mentioned numerical keypad device 35, the denomination selection panel 36 is constructed from a denomination selection panel image displayed on the liquid crystal display panel 5 d and a predetermined area of the touch panel 5 k corresponding to the denomination selection panel image.

When the player touches the touch panel 5 k corresponding to the periphery of the denomination display part 32, a denomination display selection panel image is displayed on the liquid crystal display panel 5 d as shown in FIG. 7, thereby input operation of the denomination by the denomination selection panel 36 is made effective. The denomination selection panel image 36 is provided with eleven sum display areas which are set beforehand from 1 cent to 10 dollars. The denomination is changed to the sum displayed in the sum display area that the player touches the touch panel 5 k corresponding thereto, and the sum changed and input by the player is displayed in the denomination display part 32. For example, when the player touches the touch panel 5 k corresponding to the area of “$ 1”, the sum “$ 1” changed and input is displayed in the denomination display part 32, as shown in FIG. 7. Thereafter, when the player again touches the touch panel 5 k corresponding to the periphery of the denomination display part 32, the denomination selection panel image disappears, and the denomination is recognized as one dollar by the main CPU 42. The player conducts the game by determining the bet number based on the denomination selected according to the above.

In the slot machine of the second embodiment, similarly to the first embodiment, the player can freely set the denomination without being limited to the sum which is fixed beforehand, as in the prior art. And the player can quickly operate the denomination selection panel 36 while seeing the reel display window portion 5 and operability to determine the denomination can be raised.

Here, in the second embodiment, it may be constructed so that the denomination value input through the numerical keypad device 35 and the denomination selection panel 36 is used as the denomination over a plural times of games and such denomination is used for setting the betted money. That is to say, the denomination value input in the present game by the player may be stored as the data in the RAM 44 and the like and the stored data is used as the denomination in the present game and the next games, thereby the betted sum is set. In this case, the stored data in the RAM 44 is automatically treated as the initial value of the denomination, and so long as the player does not renew the denomination, that is, the denomination value is not again input, such initial value is continued to be used as the denomination. And when the denomination value is again input through the numerical keypad device 35 or the denomination selection panel 36, the initial value may be displayed in the denomination display part 32.

According to the above construction, in a case that the constant denomination is used over a plural times of games, the player can omit the input operation of the denomination value through the numerical keypad device 35 and the denomination selection panel 36 every the unit game, thereby operation in the game can be reduced. As a result, even if the player conducts games for a long time, the player can concentrate in games without feeling fatigue and improvement of motivation for games can be expected.

And it may be determined corresponding to gaming state whether or not the denomination value input through the numerical keypad device 35 or the denomination selection panel 36 by the player is used for setting the betted money. For example, it is supposed two gaming states, in which the expectation values of the payout paid out to the player in the unit game are different with each other, and it is supposed that the gaming state with lower expectation value is the first gaming state and the gaming state with high expectation value is the second gaming state. At that time, in one of the first gaming state and the second gaming state, the denomination value input through the numerical keypad device 35 or the denomination selection panel 36 by the player is used and in the other gaming state thereof the denomination value fixedly stored in the ROM 43 is used.

According to the above construction, there may be a case that the rate for getting coins in the specific gaming state may be controlled.

And according to the gaming state, it may be conceivable that a range of the denomination value which the player can input through the numerical keypad device 35 or the denomination selection panel 36 is changed. For example, in the above first gaming state, the denomination may be selected within the range from 1 cent up to a predetermined first upper limit value (for example, 100 dollars) and in the above second gaming state, the denomination may be selected within the range from 1 cent up to a predetermined second upper limit value (for example, 10 dollars) lower than the above first upper limit value. Further, the second upper limit value may be set higher than the first upper limit value. And a lower limit value of the denomination value which the player can input may be changed according to the gaming state.

According to the above construction, there may be a case that the rate for getting coins in the specific gaming state may be controlled.

And in the above first and second embodiments, although it is explained the case that operation of the numerical keypad device 35 is detected by the numerical keypad device detection circuit 64 and the detected value is input to the main CPU 42, thereby the denomination value is determined, the present invention is not limited to this. For example, it may be conceivable that the function of the numerical keypad device detection circuit 64 is provided with the touch panel 5 k and the numerical value input through the numerical keypad device 35 is directly given to the main CPU 42 from the touch panel 5 k. According to this construction, in the cabinet to which the touch panel 5 k is installed as the standard, the slot machine having the same function as the above embodiment may be realized by only changing software thereof, without adding a new parts such as the numerical keypad device detection circuit 64.

Further, in the above embodiments, although dollar ($) and cent (¢) are utilized as the currency denomination displayed on the numerical keypad device 35 for inputting the denomination and the denomination selection panel 36 for selecting the denomination, the currency denomination is not limited to this. For example, the currency denomination displayed on the numerical keypad device 35 and the denomination selection panel 36 may be pound and penny and the like, thereby the currency denomination may be changed and displayed corresponding to the area where the slot machine 1 is used.

And in the second embodiment, although the denomination selection panel 36 is provided with eleven sum display areas set by stages between 1 cent and 10 dollars, the present invention is not limited to this. It may be constructed so that the number of the sum display areas can be voluntarily set according to the area where the slot machine is exported and the circumstance that the slot machine is used.

In each of the above mentioned modifications, the effect similar to the above mentioned embodiments may be obtained.

In the above mentioned embodiments, although it is explained a case that the gaming machine of the present invention is applied to the slot machine, the present invention can be applied to the gaming machine in which game media are betted, similar to the above embodiment. For example, the present invention can be applied to a Japanese Pachi-slot gaming machine that rotation of the reels is stopped by operating the stop buttons, a poker gaming machine, a trump gaming machine, a mah-jong gaming machine and the like, Further, the present invention can be applied to a game program by which a home gaming machine can suspectedly execute the same operation as in each of the above gaming machines. In this case, as the recording medium to record the game program, various recording media such as CD-ROM, FD (Flexible Disk), flash memory card and the like can be utilized. If the present invention is applied to any of the above gaming machines, the same effect as that of the embodiment can be obtained.

Further, the numerical keypad image may be displayed on the liquid crystal display panel 5 d every one game is terminated and when the player wants to change the bet number.

And the numerical keypad image may disappear when the touch panel 5 k corresponding to the periphery of the bet number display part 32 is touched.

Further, in a case that the numerical keypad image includes an enter key image instead of the clear key image shown in FIG. 6, the numerical keypad image may disappear at the timing that the player touches the touch panel 5 k corresponding to the enter key image.
